Chemical composition and in vitro ruminal fermentation of common tree forages in the semi-arid rangelands of Swaziland

Browse plants play an important role in providing feed for livestock in semi-arid rangelands of Africa. Chemical composition and in vitro ruminal fermentation of leaves collected from Acacia burkei, Acacia tortilis, Acacia nilotica, Dichrostachys cinerea and Ehretia obtusifolia in communal grazing lands in the lowveld of Swaziland is presented. Leaves were collected from trees located on two soil types (i.e., lithosol and vertisol) in the communal land but it had no effect on the chemical composition of tree leaves. The NDFom and ADFom content were highest in D. cinerea and A. burkei and lowest in E. obtusifolia and A. nilotica. Crude protein (CP) contents ranged between 108 g/kg and 122 g/kg DM. D. cinerea had the highest Ca and Mg content, while A. tortilis had the lowest. There were marked variations in K level amongst browse species, with A. tortilis (9.1 g/kg DM) having the highest value. The P, Zn and Fe did not differ between browse species. Soil type and tree species interaction impacted in vitro fermentation parameters. Extent of fermentation, as measured by 48 h cumulative gas production, and organic matter degradability was highest in E. obtusifolia leaves and lowest in D. cinerea leaves within soil type. Fermentation efficiency, as measured by partitioning factors, was highest in A. nilotica leaves. Leaves of E. obtusifolia could be a valuable supplementary feedstuff for ruminant livestock due to its in vitro fermentation characteristics as well as low fibre and moderate CP levels.

Sharing and speaking about African music : professional development with Swaziland primary school teachers

The teaching and learning of Indigenous African music is characterised as a holistic integrated experience where music, dance and theatre are inseparable, seen as an integral part of culture. The transmission of this experience is absorbed through participation in cultural activities from childhood in the community. In African societies, both traditional and contemporary, musical arts education and the understanding of culture are fundamental to life, community and society. It is through musical arts, that Africans embrace spiritual, emotional, material and intellectual aspects and knowledge of both the individual and the community. This paper reports on an in-service program (August 2006) offered at the Centre for Indigenous African Instrumental Music and Dance Practices (CIIMDA), Pretoria, South Africa. For the purpose of this paper, the one week professional development course undertaken by generalist primary school teachers from Swaziland is highlighted and proves worthy for these teachers to implement what they learnt in the classroom. As a position paper, I contend that the understanding and participation in indigenous cultural musical arts practices, enlightens learners about their cultural heritage and further enriches their understanding of African music and dance that can be adopted, adapted and applied to primary schools in Swaziland. This paper summaries some key findings of interview data from ten participants in relation to the intensive program. By offering such in-service professional development programs, teachers are able to reach their wider communities where they will continue to share and speak about African music, dance and culture.
